SOLID STATE CONTROLLER
WIRING INSTRUCTIONS AND DIAGRAMS
BEFORE REPLACING THERMISTOR OR SOLID
STATE HEAT CONTROLLER, PLEASE CHECK
THE FOLLOWING:
- Make sure there is sufficient water in chamber
- Check fill tube and valves for leaks
- Check heaters and all connections
- Check Overtemperature Thermostat (Part #PCT042). Reset or replace if necessary
When replacing the solid state controller or thermistor, note Serial Number of autoclave and install
per corresponding wiring diagram to the right
Solid state controller is supplied with choke and M.O.V. mounted P.C. board.
For Machines Using Both Steam and Dry Heat Sterilizing Modes
- Mount controller and rewire per wiring diagram
- Press in interlock stop button and turn temperature control fully clockwise
- Each installation REQUIRES individual adjustment to match the individual machine as follows:
- If steam and dry heat are required (dry heat door must be installed) bring temperature up
to 350°F by adjusting rheostat on P.C. board. (Note: The "Heat-On" lamp will flash before final
temperature is reached. Allow 10-15 minutes for temperature to stabilize before each adjustment.)
- Turn machine off and allow to cool
- Turn temperature control counter-clockwise until interlock button pops out. Remove knob from shaft.
- Operate machine through steam cycle. Adjust front rheostat to stabilize temperature at 270°F.
(Note: The "Heat-On" lamp will flash approximately 10° before temperature stabilizes. Allow 10-15
minutes for stabilization after each adjustment.)
- Replace temperature control knob. Make sure flange on knob is against interlock stop button
For Machines Using Steam Sterilization Only
- Mount controller and rewire per diagram
- Operate sterilizer through steam cycle with front control rheostat
turned clockwise to interlock stop button (maximum setting for steam
sterilization)
- Each installation REQUIRES individual adjustment to match the individual machine as follows:
- Adjust rheostat on side of printed circuit board until sterilizer temperature stabilizes at 270°F.
(Note: Approximately 10°F before temperature stabilizes the "Heat-
On" lamp will start flashing. Allow 10-15 minutes for stabilization
of temperature after each front control rheostat adjustment.)
- Run machine for several cycles to verify setting. Make any necessary readjustments.
